This error can be quite perplexing, but fear not; we’ll walk you through the steps to resolve it. In this article, we’ll explain what causes this error and provide a simple solution.

Understanding the Error

The error message is related to “insecure directories” and may appear when you’re using the Zsh shell after installing Homebrew. Zsh, or Z Shell, is a popular alternative to the default shell on macOS. Homebrew is a package manager for macOS, commonly used for installing and managing software packages.

There are insecure directories:

In this example, the error message indicates that /usr/local/share is an insecure directory.

Resolving the Issue

To fix the “zsh compinit: insecure directories” error, you can follow these steps:

  1. Open your Terminal.

  2. Run the following command:

compaudit | xargs chmod g-w

This command performs the following actions:

  • compaudit identifies the insecure directories.
  • xargs passes each directory to chmod g-w.
  • chmod g-w removes write permissions for the group, making the directory secure.

After executing this command, you should see an empty list when you run compaudit again.

$ compaudit
# No insecure directories (empty line)

Now, you’ve successfully resolved the “zsh compinit: insecure directories” error.
